Cat B is def better than C. My Dr says that C should only be taken if the benefits outweigh the risks, which they don't in the case of a cold. I've used Rhinocort for allergies and it was great. My insurance didn't cover it though, so I wasn't able to continue past the sample from the Dr. If you run into insurance issues, just get a prior authorization and make sure your ENT specifically states that you can't use anything else because of early pregnancy. Hope you feel better soon.
